SCREENING-BURNING GRATE AND SYSTEM.

Application filed February 25, 1922.

Toall whom it may concern:

Be it known that I, EDWARD F. SENGLAUP,

a citizen of the United States, residing at lliagara Falls, in the county of Niagara and State of New York, have invented new and useful Improvements in Screening-Burning (Jrrates and Systems, of which the following is a specification.

This invention comprehends the provision of an air cooled grate designed to burn the cheapest kind of coal dirt, commonly known as hard coal screenings.

The chief characteristic of the present invention resides in providing a. grate over the. top of which the tire burns evenly, and de signed to whirl the gases in a. circular path as the air is baffled in every angle and kept down on the grate, thus completely mixing the gases and completely burning the same.

Another important object of the invention resides in the provision of means for promoting a perfect distribution of air from every angle, thus burning the fuel and gas comple ely and evenly, the grate including a plurality of inverted cap-like members which are arranged above the openings in the grate and spaced from the latter for the purpose mentioned.

Another object of the invention resides in 30 the provision of means whereby the said cap-like members may be adjusted toward and away from the grate to suit various conditions.

In carrying out the inventioi'l, I also provide a grate structure, wherein the frame and other component parts can be readily and easily assembled or disassembled as the occasion may require.

The nature and advantages of the invention will be better understood when the following detailed description is read in connection with the accompanying drawings, the inven tion residing in the construction, combination, and arrangement of parts as claimed.

In the drawings forming part of this application, like numerals of reference indi ate similar parts in the several views, and wherein Figure 1 is a plan view of the grate con structed in accordance with the present invention.

Figure 2 is a fragmentary sectional view taken transversely of the grate bar looking in the direction of the shaking arm.

of the cap shaped members and a portion of the grate bar respectively.

Figure 1 is a view, partly in section of the shaking mechanism. 7

Figure 5 is a bottom plan view of one of the cap members removed.

Figure 6 is a fragmentary plan view of the grate with the cap shaped member removed. a

Figure 7 is a fragmentary plan view of the modified construction.

Figure 8 is a fragmentary plan view of the grate construction in the modified form.

Figure 9 is a bottom plan View of the cap member used in the modified form.

Figure 10 is a transversely sectional view through one of the cap shaped members and a portion of the grate bar which are used in the modified form. I

Referring to the drawings in detail, and particularly Figures 1 to 5 inclusive, I have shown a plurality of grate sections indicated at 10 and provided with a plurality of circular openings 11 about each of which is arranged a vertical annular flange 12. Radiatin from the wall inwardly thereof of said. opening 11 are diametrically opposed apertured lugs 13, while extended across each opening is a plate 14 having a central opening 15 for the reception of a bolt 16. The bolt includes a head 17 which is embedded in an inverted cap-shaped member 18, there being one of these for each opening 11 and arranged above the latter for the purpose of equally distributing the air over the area of the grate and completely burning the fuel and gases, maintaining the airin a whirling motion, and thus eliminating waste. For this purpose, the cap-shaped member 18 is spaced from the grate, or in other words from the flange 12 through the instrumentality of headed pins 19, the head 20 of each pin being received by a recess 21 formed in the underside of the cap member.

18. These pins not only support the memher in spaced relation to the grate, but assist in holding the member 18 rigidly in position for use, however the primary means for this purpose includes a. nut 22 threaded on the bolt 16, and a spring 23 which is interposed between the nut and the grate. The distance between each cap-shaped member 18 and the adjacent flange may be varied to suit different conditions, by simply removing the pins 19 from the apertured lugs 13 and using other pins with the proper size head. It is manifest that in the construction shown and described, that the draft air is kept in constant motion completely burning the fuel, and being equally distributed from every angle, for this purpose, thereby eliminating shooting up of the flame here and there over the area of the grate. This grate efficiently burns coal dirt, commonly known as hard coal screenings, that is marketed at less than fifty per cent of the cost of regular grade anthracite.

As illustrated, the grate frame is made up of parallel side and end members 25 and :26 respectively, and these members can be easily assembled or disassembled as the occasion requires, by reason of the fact that the end members 25 overlapthe end members 26 and are secured together by means of a bolt 27 having an elongated head 28 which is adapted to be arranged at a right angle to the slot 29 provided in the side members as clearly illustrated.

In the modified form of the invention as shown in Figures 7 to 10 inclusive the members corresponding to the lugs 13 in the preferred form are the knobs 13 which are provided with centrally disposed recesses. These knobs are formed adjacent to each corner of a substantially rectangular opening 11 which has its corners removed and rounded to conform to the curvature of the knobs. The cap shaped members 36 are rectangular shaped and depending from the central portion of each member is an ear 16 having a slot formed therein to receive a wedge 22 to hold the recess 21 formed inthe capmember in contacting engagement with the heads 20 of the pins 19.

This form of the invention distinguishes from the-preferred form as above described, but both forms in fact have their grate made up: of a plurality of grate bars which are mounted in the frame for pivotal movement so that the grate members can be moved for the purpose of cleaning the grate in the well known manner. Between the end memhere 26 of the frame are arranged the grate bars 10 which are provided with trunnions 31 journaled in suitable openings 32 in the end members 26. These bars support the grate plates 10 and above which are arranged the inverted cap-shaped members 18 or 36 as the case may be. Each plate is of the same construction as the grate described in connection with the preferred form of the invention, and possessesthe same advantages.

For the purpose of shaking the grate, I provide each grate bar 10 with an arm 37 which rises from the bar at a. right angle thereto and secured to said bar by means of a bolt 38. The arm 87 is longitudinally slotted as at 39 and in said slot is adjustably mounted a trunnion 40 adapted to be connected with the shaking rod not shown. By adjusting the trunnion 40 in the slot, the degree of movement of the grate bars can be regulated. The shaking arm can be swung to either right or left position which eliminates making right and left hand grates, and the arm is designed to cooperate with teeth which holds the arm in a given position.

While it is believed from. the foregoing description, the nature and advantages of the invention will be readily apparent, I de sire to have it understood that I do not limit myself to what is herein shown and described, and that such changes may be resorted to when desired as fall within the scope of what is claimed.

What I claim is 2- 1. A grate of the character described comprising a body including a plurality of sections, each having a plurality of openings arranged therein, headed; bolts rising from adjacent the edge of each opening, a cap shaped member provided with recesses to receive the heads in the bolts and being supported to overlie the openings in spaced relation with the edge thereof and means depending from the center of the cap shaped member and being secured to the body to hold the cap shaped member engaged with the bolts for'the purpose specified.

2. A grate'of the character described comprising a grate body having plurality of openings, apertured lugs projecting upwardly from the wall of each opening, a cap-shaped member arranged above each opening and having a. plurality of recesses, means for holding said cap-shaped member fixed with relation to the said grate, headed pins received by said lugs, and the heads of said pins being positioned in said recesses to space the cap-shaped member from the grate for the purpose specified.

' In testimony whereof I ailix my signature.

EDWARD rnanors SENGLAUP.
